extend as it were quite to the front; its sides are gently curved, and just before the 
base exhibit a more sudden though slight contraction, the hind angles being rectangular 
and scarcely at all plicate; the surface is polished and irregularly punctate, the 
punctuations being numerous and distinct along the sides, more scanty along the 
disc, except that there is on each side of the middle behind a slightly depressed 
longitudinal space, on which the punctures are somewhat larger and a little 
closer. The sixth stria at the base of the elytra curves inward so as to form a sort 
of transverse impression, and the fifth stria is continued so far forwards that it appears 
to join this impression, though really it is slightly separated; both these strice are 
very short, though continued backwards as serial punctures. ‘There is extremely 
little punctuation on the prosternum. The middle of the mesosternum is quite on a 
level with the metasternum, is polished, and has a well-marked oval fovea on the 
middle. The ventral segments are polished, with very little punctuation. The femora 
are unusually broad. 
Specimens of C. germanus were named “ C. distinctus, Guérin,” in Sallé’s collection ; 
but on comparing them with Guérin’s description, I think they are more probably an 
allied species. I have not, however, seen any example of C. distinctus from New 
Granada, the locality given by Guérin for his species.

Elongatus, angustus, niger, elytris rufis; capite prothoraceque fortiter punctatis, hoc dorso vage impresso, 
medio levigato ; elytris striis quinto sextoque discretis, ad summum basin conjunctis. 
Long. corp. 10, lat. 23 millim.; long. antennarum 43 millim. 
Hab. Guatemata, Capetillo (Champion). 
Head elongate and narrow, coarsely punctate, the median channel deep towards the 
vertex, obsolete in front. Thorax long and narrow at the base, with a well-marked, 
parallel-sided neck, the punctuation coarse. Elytra narrow, deeply striate, the fifth 
and sixth strie distinct and neatly joined at the base. Prosternum coarsely punctate 
at the sides. Mesosternum deeply foveolate on the middle. Ventral segments polished, 
almost without punctuation. One specimen. 
4, Catogenus pusillus, sp. n. 
Angustus, parallelus, capite prothoraceque fuscescentibus, crebre punctatis, illo vertice canaliculato, hoc 
posterius in medio spatio angusto levigato ; elytris striis quinto et sexto discretis. 
Long. corp. 6-7, antennarum 23 millim. 
Hab. Guatemaa, Capetillo (Champion). 
Head closely punctate, the vertex impressed ; along the middle there is a very faint 
indication of a channel. Thorax long and narrow, in front transversely convex, 
unusually coarsely punctate, with a narrow smooth space along the middle in front of 
the base; the lateral margin scarcely extends to the front; the sides are straight till
